Bitcoin Cash is not Bitcoin. It did not create new Bitcoin. It created another currency called Bitcoin Cash. Not sure what is so hard to understand from this.

Let me break it up to you again:

1. Bitcoin (In it's current form) has a limited supply. If nothing changes, there will be a time when new Bitcoin cannot be mined anymore.

2. Forking Bitcoin does not mean new Bitcoin is created. You are confusing value and supply. Forking creates an alternative currency (which can be called anything you want) that uses the former ledger of Bitcoin to distribute its initial wealth.

3. It is not a guarantee that addresses with lost secrets will be lost forever. Like you said, SHA256 exploits, or maybe quantum computing would be able to recover them.

When the fork occurred, Bitcoin's value didn't drop, and Bitcoin Cash's market cap was instantly in the billions. Everyone suddenly had more funny money, but we're somehow supposed to believe "Bitcoin isn't inflationary!" still holds.

It's going to get really exciting at tax time, when people declare bankruptcy, go into a nursing home and need to prove they don't have assets for Medicaid, etc.

> Like you said, SHA256 exploits, or maybe quantum computing would be able to recover them.

That's an insane defense of the point. Sure, if that stuff happens, you'll be able to retrieve lost coins. And non-lost coins. So will everyone else. Bitcoin's value would be instantly zero.

New value was not conjured up. A new crypto was created, but the value of it was proportional to its expected use and some other features. There are plenty of bitcoin forks, but you dont hear about the other ones as much because they flopped entirely.
